| Message: | Antonio, from Mexico, began purchasing hydraulic cartridge valves from China 3 years ago. Last September, Antonio customized a hydraulic pilot operated pressure relieving valve in Ningbo for use in their newly developed hydraulic power unit. During equipment commissioning, it was found that the internal leakage of the hydraulic pilot operated pressure relieving valve was not up to standard and the opening and closing performance was not satisfactory. The original hydraulic pressure relieving valve manufacturer has revised the samples 3 times, but none of them can satisfy their engineers. Antonio was very upset.
Antonio saw the customer case of the hydraulic pressure relieving valve released by AAK in B2B, and left a message.
